'SCHWARTZ, INCORPORATED, OF PHILADELPHIA, PENNSYLVANIA, A COItlPORA TION or PENNSYLVANIA.

Application filed May 9,

. To all ohom it concern:

Be it known that I, ELwooD B. AYREs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Driers, of which the following is a specification.

My invention relatesto certain improvev A ments -in driers for which application for patent was filed by'E. C. Faber on the .6th day of May, 1922, Serial No. 558,893.

In this drier, the material is mounted on a rota carrier and the carrier is rotated while t e material is subjected to currents of heated air.

The object of my invention is to construe a drier of the tunnel type, in which the-ma- 'terial is carried through a drying-compartment on'cars, or other carriers, while. being subjected to currents of air in such a manner as to provide means for rotating the material mounted on the cars as they pass A through the drying compartment.

- In the accompanying drawings:

Fig. 1 is a sectional plan view of a drier illustrating my invention;

Fig. 2 is an enlarged sectional plan view on the line 2-2, of Fig. 3, showing the gearing by which the carrier is turned*,

Fi 3 is a transverse sectional viewon the line 3-3, Fig. 2; and

Figs. 4, 5 and 6 are views of modifications of the invention.

Referring'to the drawings, 1 is the: casing.

' of the drier. 2, 2 are longitudinal partitions dividing the drier into three compartments a, b and c. a is the drying com partment and .b and care theheating com partments. In the latter compartments are steam coils 3?, in the present instance. Other means may be provided for heating theair,

if desired. In each partition are openings 4 and 5 for the circulation of air. Each alternate opening 4 in each partition is designed to receive a circulatin fan 6 mounte on a horizontal shaft, 'w 1ch 1s driven in any suitable manner. It will be noticed that the fans 6 on one side are opposite the openings 5 on the other side so that the is pushed into thedrying compartment, an-

and meshes with the teeth on a rack DRIER.

other car is pushed out. The openings 8 in the ends of the drier are closed by suitable doors, not shown.

9 are rotatable carriers .for the material to be dried. Each carrier is pivotally mounted on its car at 10, the pivot being adapted to suitable bearings on the car. The carriers can be constructed so that the material-can be arranged in tiers, or in any manner desired, but the arrangement should be such as-not to interfere materially with the free circulation of air in. the drying compartment. I H

"On each carrierf9 is a gear wheel 11, which meshes with the teeth of a fixed rack 12 at the side of the drying compartment.

As the cars are pushed forward, the rackbeing fixedcauses the carrirsto be turned so as to "alter the position of the material-in respect to the circulating fans. This arrangement presents difi'erent surfaces to the direct action of the currents of air as the cars are traversed through the drying compartment, thoroughly drying the material mounted on the carriers In Fig. 4 a modification is illustrated, in

which the pivot 10 of the carrier 9 extends through the car 7 and has a pinion 11, which meshes with a rack 12 between the rails of the track. This construction will cause the carrier to turn a greater dis= .the type of car used for carrying the material to be dried. I

; tance with the same movement of the car,

In Fig. 5, rails 15 are illustrated at each side of the drying chamber. The cars 7 travel on these rails.

Suspended from the I cars are carriers 9 by the shaft 10', whlchhas at its upper end a gear wheel 11", mesh- ,ing-with a fixed rack 12". A carrier, in this instance, has a series of platforms on which the material to be dried can be placed.

In Fig. 6, rails 15 are shown suspended from theroo f of the drying compartment. The carrier 9 may be guided by a bottom rail 16, as shown. The gear wheel 11' is secured to the shaft 10 above the carig secured to the roof.

I claim:

1. The combination of a drier having a longitudinal drying compartment; means for circulating heated air in said compartment; carsarranged to travel through the compartment; .a carrier mounted on each car; and 'means. for imparting a rotary movement to the carriers as the cars travel through the compartment of the drier.

2. The combination of a drierhaving a longitudinal drying compartment; means for circulating heated air across the drying compartment; a longitudinal track in the drying compartment; a series of cars on the track; a rotatable carr er on each car;

and means forrotating the carriers as the cars move longitudinally through the drying compartment.

3. The combination in a drier, of a longitudinal drying compartment; means for circulating air in the compartment cars arrangedto travel through the compartment; .a-carrier on each car; a gear wheel on'each compartments,. the central compartment bemg a drying compartment and the side compartments being heating compartments; circulating fans located in the partitions so as to cause the air to circulate across the drying compartment; a longitudinal track in the drying compartment; a series of cars mounted on the track; a carrier on each car; a gear Wheel on each carrier; and a longltudlnal rack with which the gear wheels engage so that, as the carsare moved through the drying compartment, the car- I riers are turned.
